SAFE DEPOS IT LOCK Filed July '28, 1928 ATTORNEY Patented Apr. 18, 1933 UNITED STATES.

PATENT r OFFICE WILLIAM r. MOSELY, on STAMFORD, coNNncrroUr, AssIGNoR ro THE YALE & TOWNE MANUFACTURING COMPANY, or STAMFORD, CONNECTICUT SAFE nnrofsrr LOCK Application filed July 28,

My invention relates to improvements in safety deposit locks and is a modlficatlon of my invention described in Patent 1,432,720 for a safety deposit lock issued October 17,

' tion, I shall now refer to the drawing wherein are shown two modificationsof my invention. Fig. 1 is a top view of a washer comprising part of my invention, while Fig.2 is an elevation of a screw comprising the invention and shown in cooperation with the washer. Figs. 3 and 4 are end and elevation views of the screw, comprising a modification of the invention illustrated in Figs. 1 and 2. Fig. 5 is a view of the back plate of a safe deposit box showing the invention applied thereto. Fig. 6 is a front view of the lock with the cover removed, showing the tumbler arrangement. 7

While I will describe below the invention as shown in this application, a perusual of my patent, indicated above, will be helpful insofar as it indicates in more detail the significance of the invention described herein.

As .shown in Figs. 1 and 2, I have found it expedient to employ a washer 10 which is adapted to carry the key designated character L150. This washer is held under the head of the screw 11 which maintains the washer against the casing 15 as is clearly shown in Fig. 5. \Vhen the screw is in its operative position seouredto the bolt 14 by means of the screw-threaded portion 14a, its extension 13a is adapted to hold the tumblers inactive.

as illustrated in Fig. 6, and the designating character 4150 will be held in a concealed position as is clear from Fig. 5. It is then f necessary to remove the screw and release the various tumblersso that the washer may be 1923. 'Serial Ito 296,048. I ,7

withdrawn and exposed to View in order that the key designation be read.

Figs. 3 and t show a modification of Figs. 1 and 2, in which the key design'atingcharacter is carried on the rear. face 12- of the screw 11. It fis'quite obvious that the character' 41 50 .willthus be held concealed as long as the screwis'maintai-ned in its active position. for maintaining-the tumblers 13 inoperative. Thus, the underlying principle of the invention is the maintenance of the designating'charaoter out of view by utilizing directly the means which holdthe lock inoperative. y Y While I have shown two modifications of my invention, it is quite evident that other variationsof the same within the scope of the appended claims will occur readily to those skilled inthe art. v
